This TMNT mini papercraft is the Michelangelo, created by Gus Santome. Michelangelo (Mike or Mikey) is a fictional character and one of the four main characters of the Teenage Mutant Ninja Turtles comics and all related media. His mask is typically portrayed as orange outside of the Mirage/Image/IDW comic series and his weapons are dual nunchaku, though he has also been portrayed using other weapons, such as a grappling hook, tonfa, and a three section staff.
More fun-loving than his brothers, Michelangelo was given a much bigger role in the 1987 cartoon series, directed at a younger audience, than in the more serious original comic books which was aimed at an older audience. He came to epitomize the late 1980s and early 1990s popular culture incarnation of the TMNT, coining most of their catchphrases. Like all of the brothers, he is named after a famous Renaissance artist; in this case, he is the namesake of Michelangelo Buonarroti, who was the painter of the ceiling of the Sistine Chapel. The spelling of the character's name varies from source to source, and he has been alternately shown as both Michelangelo and Michaelangelo.
